Monocoque Unified Carbon Shell

Unlike 99% of carbon frames, which are produced by bonding multiple carbon tubes and pieces, SWI utilises a unique patented, full monocoque construction process, which uses a single mould and produces a finished frame as a single uninterrupted carbon shell. This results in a lighter, stiffer, stronger, and more precisely aligned frame than is possible with bonding.

NTPT™ Carbon Textile

NTPT™ Carbon Textile

The AEQUUS is constructed using high-performance carbon textiles from the Swiss-based composite supplier North Thin Ply Technology (NTPT). SWI is the only bicycle manufacturer in the world utilizing NTPT high-performance carbon textiles, which have an exceptionally dense unidirectional carbon weave of up to 29 ply, while the average carbon fibre fabric is only 4 to 5 ply. As a result, the NTPT fabric produces a significantly higher stiffness-to-weight ratio than typically seen in frame manufacturing.
